Abstract

Gastrodin is a major active phenolic glycoside extract from Gastrodia elata, an important herb used in traditional medicine. Previous research has reported that gastrodin possesses anti-inflammatory and anti-oxidant properties. Therefore, we aimed to investigate its hepatoprotective effects and mechanisms on acetaminophen (APAP)-induced liver injury in a mouse model. Mice included in this study were intraperitoneally administered with a hepatotoxic APAP dose (300 mg/kg). At 30 min after APAP administration, gastrodin was intraperitoneally injected at concentrations of 0, 15, 30, and 45 mg/kg. Then, all mice were sacrificed at 16 h after APAP injection for further analysis. The results showed that gastrodin treatment ameliorated acute liver injury caused by APAP, as indicated by serum alanine aminotransferase level, hepatic myeloperoxidase activity, and cytokine (TNF-α, IL-1β, and IL-6) production. It also significantly decreased hepatic malondialdehyde activity but increased superoxide dismutase activity. In addition, gastrodin decreased ERK/JNK MAPK expression but promoted Nrf2 expression. These results demonstrated that gastrodin may be a potential therapeutic target for the prevention of APAP-induced hepatotoxicity via amelioration of the inflammatory response and oxidative stress, inhibition of ERK/JNK MAPK signaling pathways, and activation of Nrf2 expression levels.
